Third Tesla Fire Singes TSLA Stock

There were no injuries in any of the incidents

Shares of Tesla Motors (TSLA) slumped more than 3% in Friday morning trading in the wake of reports of a third fire involving one of its pricey electric cars.

In the latest incident, a driver hit road debris near Smyrna, Tenn., sparking a fire in his Model S. On Thursday, federal regulators signaled that they planned to investigate the fire, USA Today reports.

TSLA stock was already hurting this week after the company released third-quarter results. While profits more than doubled and beat analyst expectations, vehicle sales disappointed Wall Street forecasts, as did the company’s earnings outlook. TSLA shares are off 17% this week.
